I have the following, additional comments to section 6: 1) Is the intent that the main RTP stream in the SPLICE group is always the= one with the splicing-interval extmap attribute, and the substitutive RTP = is the other one? If so, I think being explicit about that could be helpful= . You have marked that with an i=3D line in the example, but do not require= it formally, and I also think you cannot require a parser to rely on i=3D = information to choose which is which. 2) I think it may be helpful to say that can there MUST NOT be more than tw= o m-lines in a single SPLICE group. If there would be more, you obviously c= annot know which RTP m-line to splice in at the splice point. 3) I think it may be helpful to say that a single m-line MUST NOT be part o= f more than a single SPLICE group. 4) s/FID/SPLICE/ 5) In 6.3, SDP offer, should the substitutive video be sendonly, or is it i= ntentionally sendrecv? It is sendrecv also in the SDP answer, so if it is i= ntentional, it is formally OK between offer and answer. 6) In 6.3, SDP answer, the substitutive audio is marked as sendonly, but sh= ould be recvonly to match the offer. 7) Editorial nits: Near the end of section 2: s/sllowing/allowing/ Near beginning of section 6: s/This document extended/ This document extend= s/ Cheers, Bo > -----Original Message----- > From: avtext [mailto:avtext-bounces@ietf.org] On Behalf Of Jonathan Lenno= x > Sent: den 31 mars 2015 16:27 > To: avtext@ietf.org > Cc: avtext-chairs@tools.ietf.org; draft-ietf-avtext-splicing-notification= @tools.ietf.org > Subject: [avtext] WGLC for draft-ietf-avtext-splicing-notification-01 >=20 > This is to announce a 3 week Working Group Last Call for >=20 > draft-ietf-avtext-splicing-notification-01 >=20 > as proposed standard. >=20 > Please review and provide any comments you may have on the document by Tu= esday, April 21, 2015.

I had similar comments to Bo around use of the = grouping framework, signalling what is the main and which is the = substitutive stream, and behaviour when there are more than two streams = in the splicing group. I also noticed that Section 3.2, last paragraph, says "MAY NOT", which = is not an RFC 2119 keyword. Is this intended to be MUST NOT, SHOULD NOT, = or something else entirely?

I have reviewed this draft. And I think it's in a good = shape. I only have several minor editorial comments as = following:

 

1. In Section 6, 3th Paragraph, last sentence " This = semantics is to have splicing applicable for BUNDLE cases" doesn't = read smoothly. Would it be better to just change to " This = semantics is also applicable for BUNDLE cases " = ?

 

2. In Section 7, last paragraph. I can't find the reference = for [SRTP-ENCR-HDR]. Is it already a published = RFC?

 

3. Some references in Section 10 have never been referred = to.

Hello Bo & Azam,=

when trying to figure out the exact protocol beha= viour in the protocol endpoints of the RTP sender and RTP receiver entities= , then we ended always in state models, which essentially allow to concentr= ate the entire specification “in a single place” (which is so far distribute over clauses 5, 6 and 8).<= o:p>

Thus, Fig. 4 “RTP pause states” is th= e key part at RTP sender side.

Two comments/questions:

1) the RTP sender state model seems to be not ful= ly complete, thus, supposing that the Fig. just highlights the major state = transitions, right?

2) a RTP receiver state model is missing, - why?<= o:p>

 

FYI: above contribution AVD-4696 provides a new p= roposed Appendix for ITU-T H.248.PAURES related to state modeling and above= questions.

Thus, Fig. 4 "RTP pause states" is the key part at RTP sender side. Two comments/questions: 1) the RTP sender state model seems to be not fully complete, thus, suppos= ing that the Fig. just highlights the major state transitions, right? [BoB] Figure 4 is not intended as an RTP sender state model, but describes = RTP stream states. This is stated in the first sentence of section 6, just = above Figure 4. There is no intention to make this state model "complete", = like describing all possible events and actions as state transitions, so th= e answer to your question is "yes". Figure 4 is included to describe what i= s actually new RTP stream states compared to RFC 3550, give structure to th= e text, and (hopefully) enhance the reader's understanding. The figure is i= ntentionally kept simple for clarity, for example omitting transitions for = staying in the same state - one reason being that ASCII art with a lot of i= nformation is somewhat hard to keep simple. The RTP sender and receiver det= ails are instead provided as text in section 8. 2) a RTP receiver state model is missing, - why? [BoB] For the same reason as above; the state model applies to the RTP stre= am itself. This is unambiguous, since an RTP stream is always uni-direction= al. FYI: above contribution AVD-4696 provides a new proposed Appendix for ITU-T= H.248.PAURES related to state modeling and above questions.

Hello Christian,

perhaps you noticed already = that we’ve submitted early contributions based on a review and consid= eration of specific use cases for H.248 IP-to-IP media gateways (besides th= e obvious primary scenarios for H.248 media servers).

Hello Bo & Azam,=

when trying to figure out th= e exact protocol behaviour in the protocol endpoints of the RTP sender and = RTP receiver entities, then we ended always in state models, which essentia= lly allow to concentrate the entire specification “in a single place” (which is so far distribute = over clauses 5, 6 and 8).

Thus, Fig. 4 “RTP paus= e states” is the key part at RTP sender side.

Two comments/questions:=

1= )  the RTP sender state mo= del seems to be not fully complete, thus, supposing that the Fig. just high= lights the major state transitions, right?

[= BoB] Figure 4 is not intended as an RTP sender state model, but describes RTP stream states. This is = stated in the first sentence of section 6, just above Figure 4. There is no= intention to make this state model “complete”, like describing= all possible events and actions as state transitions, so the answer to your question is “yes”. Figure 4 is included = to describe what is actually new RTP stream states compared to RFC 3550, gi= ve structure to the text, and (hopefully) enhance the reader’s unders= tanding. The figure is intentionally kept simple for clarity, for example omitting transitions for staying in the same state &#= 8211; one reason being that ASCII art with a lot of information is somewhat= hard to keep simple. The RTP sender and receiver details are instead provi= ded as text in section 8.

2)  a RTP receiver state mo= del is missing, - why?

[= BoB] For the same reason as above; the state model applies to the RTP strea= m itself. This is unambiguous, since an RTP stream is always uni-directional.<= o:p>

 

FYI: above contribution AVD-= 4696 provides a new proposed Appendix for ITU-T H.248.PAURES related to sta= te modeling and above questions.

Albrecht

Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Audio/Video Transport Extensions Working Group of the IETF. Title : RTP/RTCP extension for RTP Splicing Notification Authors : Jinwei Xia Roni Even Rachel Huang Lingli Deng Filename : draft-ietf-avtext-splicing-notification-02.txt Pages : 17 Date : 2015-04-28 Abstract: Content splicing is a process that replaces the content of a main multimedia stream with other multimedia content, and delivers the substitutive multimedia content to the receivers for a period of time. The splicer is designed to handle RTP splicing and needs to know when to start and end the splicing. This memo defines two RTP/RTCP extensions to indicate the splicing related information to the splicer: an RTP header extension that conveys the information in-band and an RTCP packet that conveys the information out-of-band. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-avtext-splicing-notification/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-avtext-splicing-notification-02 A diff from the previous version is available at: https:https://www.ietf.org/rfcdiff?url2=draft-ietf-avtext-splicing-notification-02 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
